Interruptions, defects and errors of human perception are the subjectsof all the works in "Die Fehler", which as such are part of atradition of scientific studies of visual impairments which were usedespecially in the second half of the nineteenth century as an area ofexperimentation by artists of the avantgarde. Research into thecomplexity of image processing was fed back into the production of theimage itself. Errors differ from norms - but who decides what is what?What is the norm and what is an error?

"Die Fehler" not only deals with our own habits of visual perceptionand the image politics that surround us, but also reflects on thevisual worlds which we, as set-designers, continually generate. Therepeated sampling of images, the use of visual quotations as well asplaying with their readability are key elements of a set-designer'swork. As Erwin Panofsky proposed as early as 1927, working with imagesmust always be understood as a form of cultural construction.
